Michi Mutsuzaki commented on ZOOKEEPER-1870:
--------------------------------------------
Ok I think I know what the problem is. There is race between
QuorumCnxManager.Listener.run() and QuorumCnxManager.Listener.halt() that
causes the socket to leak.
1. {{QuorumCnxManager.Listener.run()}} goes into the while loop
{{while((!shutdown) && (numRetries < 3))}}
2. {{QuorumCnxManager.halt()}} gets called, sets {{shutdown}} to {{true}} and
calls {{QuorumCnxManager.Listener.halt()}}.
3. {{QuorumCnxManager.Listener.halt()}} closes the socket.
4. {{QuorumCnxManager.Listener.run()}} binds the socket and breaks out of the
while loop since the shutdown flag is set.
I'll upload a patch.
